Abstract
An optical fiber whose chromatic dispersions have an opposite sign relative to those of the 1380 nm zero-dispersion fiber at all of the wavelengths in the range of 1450 nm to 1620 nm is provided. This optical fiber has negative chromatic dispersions at all of the wavelengths in this range and the values of which are −7 ps·nm ·km or more but −1 ps·nm ·km or less at a wavelength of 1450 nm, −12 ps·nm ·km or more but −5 ps·nm ·km or less at a wavelength of 1550 nm and −17 ps·nm ·km or more but −6 ps·nm ·km or less at a wavelength of 1620 nm. This optical fiber can compensate the dispersions of 1380 nm zero-dispersion fiber over the entire wavelength in this range.
